  "title": "GitHub Copilot is now available in the AI SDK harness layer",
  "why_included": "A shared HarnessAgent adapter lets builders compare Copilot with other coding harnesses without rewriting application integration code.",
  "summary": "AI SDK now runs GitHub Copilot behind the same HarnessAgent interface as nine other coding harnesses, using an official adapter and ACP connection.",
  "practical_implication": "If your application already targets HarnessAgent, use the adapter boundary to test Copilot without rewriting application-level agent integration code. Keep agent-specific behavior behind that shared interface.",
  "agent_context": "The AI SDK harness layer adds GitHub Copilot through **@ai-sdk/harness-github-copilot**. It connects to HarnessAgent through **Agent Client Protocol (ACP)** and joins nine other named harnesses, including Claude Code, Codex, and Cursor.\n\nIf your application already targets HarnessAgent, use the adapter boundary to test Copilot without rewriting application-level agent integration code. Keep agent-specific behavior behind that shared interface.\n\nA common interface reduces switching cost but does not establish behavioral parity. The material gives no compatibility matrix, feature differences, or migration constraints across the supported harnesses.",
